A brief description of when and why the water use baseline was adopted:

Past HWS President Mark Gearan signed the ACUPCC in September of 2007. Based on this, HWS established fiscal year 2007 (FY07), the year just prior to signing the commitment, as the standard baseline year for all sustainability indicators for which data is available. However, for our waste and water data we used FY 2008 due to having more complete and comprehensive data.

Optional Fields

A brief description of the institution's water-related behavior change initiatives:

---

A brief description of the institution's water recovery and reuse initiatives:

The Colleges have installed one green roof on the Gearan Center for the Performing Arts and one on a residential hall (Comstock Hall). The pilot projects were initiated by students and the Climate Task Force as a means to help with stormwater management, reduce heat island effect, extend the lifetime of the roof system, and improve energy efficiency through increased insulation value. Rain barrels are deployed across campus and captured water has been used to water gardens and other vegetation.

A brief description of the institution's initiatives to replace plumbing fixtures, fittings, appliances, equipment, and systems with water-efficient alternatives:

All major building renovations and new construction on campus utilize water efficient fixtures, including low flow toilets, faucets and showerheads. For instance, new tank style toilet installations, as well as replacements or upgrades are low flow (1.3 gallons per flush) models (approximately 170). 80% of the remaining flushometer style toilets have been upgraded to low flow valves (1.6 gallons per flush). There are approximately 300 showers on campus. Most of the existing (95%) and any new showers utilize low flow (1.5 GPM) heads. Lastly, the Finger Lakes Institute recently installed two dual flush toilets as a pilot project for campus.
